You know that famous saying "when pigs fly"?  As in something that will never happen.  Like I'll be the king of Mars when pigs fly.  Well, airplanes have existed for quite some time now and I'm sure at some point pigs have been transported in them.  So technically pigs have already flown.  Just saying any outlandish claim you want to make, if you attach when pigs fly to it, it's already happened.  You know, technically speaking.
